SPECIFICATION forming part of Letters Patent No. 280,803, dated July 10, 1883.

Application filed October 10, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. DEARBORN, of East Boston, in the county of Suffolk, of the State of Massachusetts, have invented a new and useful Improvement in Window-Jacks; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of W11l0h Figure 1 is a top view, Fig. 2 an end elevation, and Fig. 3 a rear elevation, of a windowjack embodying my invention, the nature of which is defined in the claims hereinafter pre- Fig. 4 is a vertical section of a window with the jack applied thereto.

The jack is to support a person on the outer side of the window of a house while in the act of cleaning a pane or panes of the sashes of such window. I

In the drawings, A and A are two metallic rods, bent in manner as shown, arranged parallel to each other, and having attached to them a board or bearing, B, cushioned or lined I provided with a screw, 0, to clamp it to the rod. These legs project upward above the two rods, and are connected by a board or guard, F.-

Instead of having the clamp-screw, there may be a series of holes made in the part of each rod that extends rearward beyond the platform, such holes being made at equal distances apart. A pin inserted in a hole of each rod, and close against the leg thereof, will suffice to keep the leg in its correct position.

The object of having the guard and legs adjustable 011 the rods is to adapt the jack to windows in general, or of different thicknesses, as when the jack is adapted to a window the board or bearing D is to rest on the sill thereof, the board B bearing against the inner face of the wall below the window, and the feet of the legs resting against the outer face of the wall, all being as shown in Fig. 4..

I claiml. The window-jack consisting of the two bent rods A, their connecting-bearer B, platform C, and the adjustable legs E, applied to such rods, as set forth.

2. The window-jack consisting of the two bent rods A, their connecting-bearer B, platform C, and the adjustable legs E and their connecting-guard F, all being arranged and adapted substantially as set forth.

3. The combination of the two bent rods A, their connecting-bearer B, the platform 0, auxiliary or sill bearer D, and the adjustable legs E, all arranged and adapted substantially as set forth.

4. The combination of the two bent rods A, their connecting-bearer B, platform .0, sillbearer D, adjustable legs E, and their connecting-guard F, all arranged and adapted substantially as and for use as described.
